# Errata List for Solutions to the International Edition of Computer Errata List for End-of-Chapter Questions in the

International Edition of Computer Networking, 5 th

Edition, by Kurose/Ross

Chapter 1

P1

Refers to Figure 1.8; this should be Figure 1.12.

P9

“In the above problem” should refer to problem P12.

Comments: Otherwise, the problem description is inconsistent so there is no solution.

P13.

Parts a) and b) should be switched.

P17

Refers to Figure 1.16(b); this should be Figure 1.20(b).

P18

Refers to problem P17; this should be P23.

Comments: Otherwise, this problem has no solution as P17 does not give any distance, which is required for finding delay.

P19

Refers to problem P17; this should be P23.

P21

Refers to problem P17; this should be P23.

P22

Parts a) and b) should be switched because of the dependency.

P24

Parts b) and c) should be switched, and Figure 1.28 should feature a packet symbol at each of the

4 points in the line, as shown below.

Chapter 2

P12

Part a). There is an editing mistake. The £ sign should be changed to ≤

Part c). “ ≥ ” is missing between u_s/N^3 and d_min.

Also b) and c) should be switched, because b) actually depends on c).

P15

Part b). The full problem description should be as follows:

Complete the following transaction:

C: list

S: 1 498

S: 2 912

S: .

C: retr 1

S: blah blah ...

S: ……….blah

S: .

?

?

Chapter 3

R14

Part f). “ ≥ sec” should be “ ≥ 1 sec”.

P33

Refers to Figure 3.55; this should be 3.56 in both instances.

P39

Part b). “s/R + RTT > 4 S/R” should be “8 S/R > s/R + RTT > 4 S/R”.

Chapter 4

P27

Ignore part c), as s is not in the figure.

P30

The image of the network is missing. It is pictured below.

P33

“eight-node” should be “seven-node”; “s to z” should be “t to z”; “at s that” should be “at z that”

Comments: There is no s in the referenced figure.

P35

Refers to Figure 4.45; this should be 4.44 in both instances.

P37

Refers to Figure 4.47; this should be 4.46.

Chapter 5

P6

Part a): “N 10” should be “N=10”

Part b). “N 25” should be “N=25”

Part c). “N 50” should be “N=50”

P11

Part b). “found in (b)” should be “found in (c)”.

Alternatively, “found in (b)” can be “that maximizes the efficiency for fixed N”. In that case, remove c), as c) is now contained in b).

Comments: Parts b) and c) are swapped, which causes problems. Part b) refers to itself

(“using … found in (b), …”.), and solving b) actually depends on the solution of c).

P24

Refers to Figure 5.37; this should be Figure 5.36.

Chapter 6

P16

Refers to Figure 6.21; this should be Figure 6.22.

Refers to Figure 6.22; this should be Figure 6.23.

Chapter 8

P5

Refers to Figure 8.21; this should be Figure 8.19.

P10

Refers to Figure 8.24; this should be Figure 8.22.
